SUNPOW OT-MD17 Metal Detector with 30 cm Waterproof Coil

The SUNPOW OT-MD17 is an adjustable metal detector with five detection modes and a waterproof search coil. Its listed 50 cm to 150 cm length range and backlit LCD claims make it suited to users wanting a configurable detector for outdoor searching, but the listing gives conflicting coil sizes and an unconfirmed detection-depth claim.

What to know before buying

Listing details to confirm

Listing details conflict on coil size: the title and feature text claim a 30 cm or 12-inch coil, while the technical details list a 12 Centimetres search coil. The 10-inch detection depth appears only as a feature claim and is unconfirmed. The control box is explicitly not waterproof, so the waterproof-coil claim does not mean the whole detector can be submerged. Check the selected listing for the intended coil specification before buying.

Who is it for?

A good fit for

Adults seeking an adjustable metal detector for outdoor searches who value multiple detection modes and a backlit display.
Buyers who need a waterproof coil for beach or damp-ground searching and can keep the control box dry.

Less suited to

Anyone needing a fully waterproof detector for underwater use, as the listing says the control box is not waterproof.
Buyers who require a clearly confirmed coil size or detection depth before purchase.

Customer feedback describes the detector as easy to use, enjoyable and accurate, with positive comments about its perceived build quality. These reports may appeal to hobby users, but they do not verify detection performance or settle the listing’s conflicting coil-size information. Aggregate ratings are generally favourable, though ratings alone do not explain less positive experiences.

Frequently asked questions

Can the SUNPOW OT-MD17 be used underwater?

The listing claims the coil is waterproof but explicitly says the control box is not. It does not support treating the complete detector as suitable for underwater use.

How long can the detector be adjusted?

The title gives an adjustable range of 50 cm to 150 cm. The feature text also describes a 19-inch to 59-inch range.

What size is the search coil?

The title and feature text claim 30 cm or 12 inches, while the technical details list 12 Centimetres. Confirm the coil size for the selected listing.

Is the claimed 10-inch detection depth a confirmed specification?

No. It appears in feature text, but it is not corroborated by the technical details, so treat it as an unconfirmed listing claim.
